Abdul Aziz Bek, head of the Badghis provincial council, said one military base was targeted, in the district of Balamerghab.

"Large numbers of Taliban came from several directions," Bek said. "After hours of heavy fighting 30 Afghan security forces were killed and the Taliban captured the base."

Fifteen Taliban were killed in other areas of the province overnight, he said, adding that the fighters prepared their attacks and did reconnaissance of the area during their ceasefire.

Preconditions for peace talks

The Taliban's three-day ceasefire ended on Sunday.

The Islamic State of Iraq and the Levant (ISIL, also known as ISIS) claimed responsibility for a blast in Nangarhar province that left at least 36 dead on June 17, bringing the death toll to more than 50 during the ceasefire period.

In the statement on Sunday, the Taliban repeated their preconditions for peace talks, including that they would only negotiate directly with the US and that foreign forces should leave Afghanistan.

Taliban has waged a bloody armed rebellion against Western-backed Afghan government since it was deposed by the US-led NATO forces in 2001.
